I've given up on IPsec for the time being...at least until I have a chance to talk with kion about his setup...what versions of things he's using, etc. Failing that, I'm going to do what I probably should have done back when this first started happening -- and file a bug report. (Well, send an email to a mailinglist, and hope it doesn't get ignored. The FreeS/WAN people don't use Bugzilla, for whatever reason.)
The Gentoo kernel is still being ass, for whatever reason (soundcard). I'm going to have to work on that tomorrow, along with finishing cleaning the apartment, getting my laundry done, and working.
Yeah...I have plenty to do tomorrow...and I still need to figure out what to get kion for his birthday.
